ABSTRACT

A total of 91 consecutive patients had been treated with 2.25-mm diameter SES for 112 de novo lesions during the first 6 months of enrolment in RESEARCH. Among these 91 patients, 60 patients had also lesions treated with SES (2.5 mm diameter (n=109 lesions) (average stent diameter in these lesions 2.9±0.2 mm). The angiographic outcomes of lesions treated with larger SES were utilized as a reference for comparison with lesions treated with 2.25-mm SES.
